TOP-ROLL SADDLE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 342,778, dated June 1. 1886.

Application filed July 11 1893. Serial No. 100,487. (No model.)

To all whom it may concern.-

Be it known that we, EDGAR J. CARROLL, ELBERT H. CARROLL, and WILLIAM T. CAR- ROLL, citizens of the United States, residing at XVorccster, in the county of W'orcester and State of Massachusetts, have invented certain new and useful Improvements in Top-Roll Saddles for Spinning-lilachines; and we declare the following to be a description of our IO said invention, sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying draw-, ings, which form a part of this specification. I 5 The object of our present invention is to provide a practical and convenient top-roll and saddle device for the drawing-rolls employed in various kinds of roving-machinessuch as drawing-frames, railway-heads, slub- 2o bers, Speeders, mules, ring-spinners, &c.for feeding, Working, or drawing the sliver, or roving; and our invention consists in mechanism the nature and construction of which is herein illustrated and explained, the particular features claimed being hereinafter definitely specified.

In the drawings, Figure l is an end view of our improved top-roll and saddle device, with diagrammatic lines indicating the middle,

back, and lower rolls and rear saddle. Fig.

2 is a sectional elevation showing a top drawing-roll, constructed in accordance with myinvention, together with a portion of the end bearings. Fig. 3 is a plan view of the same, partly in section. Fig. 4 is atransverse section thereof, on line or :0, Fig. 2. Fig. 5 is a transverse section of the boss and its lining. Fig. 6 is a plan view of two bosses and their arbor and saddle. Fig. 7 is a longitudinal 4o sectional View showing the bearings on the arbor made shorter than the bosses, which latter are made closed at their outer ends. Fig. 8 is an end view of the arbor when made as in Fig. 7. Fig. 9 is a transverse section of a boss and its arbor, on line y 3 Fig. 6.

In drawing-frames, roving-machines, and spinning-machines, as now commonly eonstrueted, the covered top rolls are fixed to the shafts or arbors which carry them, and the arbor of the front top-rolls is retained in its bearings and pressed down upon the roving and under roll by means of a loose saddle, the forward end of which rests uponthe arbor, which is free to revolve beneath it, while its rear end rests upon a second saddle, which in turn acts in similar manner to retain the shafts or arbors of the middle and back top rolls, the. saddles being pressed down upon the parts by means of a link looped over the first saddle .and connected at its lower end with a weighted 6o lever that is adapted, by adjusting the weight, to give the pressure required.

In this our invention the arbor A, for the front top rolls in the set of drawing-rolls, is made with the saddle C rigidly attached or forming an integral part of the arbor, the parts A and C being cast together in a single piece, and finished in the form shown, so that the arbor is provided with a rigid and permanent saddle-arm extending out from its cen- 7o tral portion in a plane perpendicular to the axis of the roll-bearings. The arbor is also provided with a longitudinal. chamber or oilehannel, a, the opening (1 into which is at the front end of the saddle or arm C, while ducts or passages, as at I), afford means for the flow of oil to the bearingsnrfaces between the arbor and bosses B.

The arbor A may be made slightly rounding on the length of its bearings,- so that boss B can have a little rocking motion in its length, if desired. 1

The shells or bosses B are provided with independent linings of brass or other suitable bearing metal, as shown at f, to enable the said bosses to run with the least wear on the iron arbors.

The arbor A maybe made with its bearings A shorter than the bosses B, and the bosses may be made closed or solid at their outer ends, as shown in Fig. 7, the chamber a being extended through the arbor to the end of the bearing, so that oil will flow into the interior of the thimble-formed boss B from the open end of the arbor-bearing.

The bearings A on the arbor can be made slightly conical, and the bosses provided with a correspondiugly-shaped bearing-cavity, the parts fitting together as shown in Fig. 7, the outer or closed end of said bosses being provided with supporting-hubs, as at B, or otherwise suitably shaped to form a bearing that will assist in keeping the rolls in proper relaftive position when in operation on the machine. The hearing may be reduced or chambered by a groove cut around its neck, as at a, which groove may contain a soft oil-absorbent packing, or be left free and open, as preferred. i

In ordinary top rolls, where the saddle rests on the shaft or arbor and the latter revolves, roving and 'aste winds on or accumulates at the junction of the saddle and the said shaft, and the operator has, as a rule, to pick the bearings, as it is called, at the end of the saddle twice each day, which requires time; but such operation is rendered unnecessary by fixing the saddle C rigidly to the arbor A, which remains stationary.

L, M, and R indicate, respectively, the lower front, middle, and rear rolls of the set, and S the second saddle, while P and P denote the upper middle and rear rolls; w, the weightinglink, and E the bearings for the ends of the arbor, which several parts may be of ordinary or any suitable construction.

\Vhat we claim as of our invention, and desire to secure by Letters Patent, is-

1. An arbor for the top drawing rolls of roving and spinning machines, having an arm or saddle formed integral therewith, substantially as and for the purpose set forth.

2. A chambered or hollow arbor for the top drawing-rolls in roving and spinning ma chines, having an integral or rigidly-attached saddle-arm, in combination with the shell bosses mounted thereon, substantially as shown and described.

3. The arbor A, having the saddle 0 formed integral with the body thereof and provided with a channel for conducting oil to its bearings, and the covered shell-bosses B, mounted for rotation thereon, in combination with the bearings and lower drawing-rolls in a spinning or roving machine, for the purposes set forth.

4. The combination, substantially as hereinbefore described, of the shell-bosses B, having independent linings f, the stationary supporting-arbor A and fixed saddle C, the lower rolls L, journal-supports E, and weighting devices, for the purpose set forth.

5. A roll or shell for roving and spinning machines, formed with a bearing-cavity at one end and a solid or closed end at the other, in combination with a supporting-arbor and the lower drawing-rolls, the roll-supporting bearings, and weighting devices employcdin aspinning or roving machine, for the purposes set forth.

6. A hollow arbor having a central ly-located oiling-hole, in combination with rolls having a closed end fitting over the ends of said arbor and revoluble thereon, substantially as set forth.

7. A hollow arbor having conical hearings,

- in combination with a pair of bosses, each pro- .vided with a correspondiugly-conical. cavity at one end and a supporting hub or hearing at the other end, substantially as shown and described.

\Vitness our hands this 6th day of July, A. D. 1883.
